hi,i`m fitting mt own kitchen,but not certain whats best to go against the walls first?..the backboards,then the worktops fitting up to them,or the worktops against the walls,then the backboards fitting on top of the worktops?
always fit the worktops first, then but the backs down on top. It a good idea to seal all the cuts on the tops and the backs to seal with P.V.A it's also a good idea to put a bead of sealant between back and top.
